Abstract: A liquid fuel injection spoke for a gas turbine engine. The liquid fuel injection spoke may include an inlet end and an outlet end. The liquid fuel injection spoke may further include a head located at the inlet end and a stem extending along a longitudinal axis from the head to the outlet end. The stem may define a fluid passageway therein. The head may include a cavity with an inner wall. The inner wall may include an annular protrusion.

Abstract: This present invention covers novel means, devices and instruments for production of a tissue array block that is further sectioned into duplicates of tissue arrays. An integral microscope is incorporated into the instrument for viewing and examining a stained reference slide and selecting donor tissue core region(s) from the reference slide. The reference slide is held in a reference slide station that is operatively linked and indexed with a station or platform holding a source donor tissue block, which is further indexed and precisely positioned with reference to the donor needle punch for punching the donor tissue core(s). A recipient block indexed to the donor block punch is placed under the donor punch station and donor tissue cores are delivered into pre-existing hole(s) by a stylet to construct the tissue array block. The instrument includes a donor punch station, optionally a second recipient punch station, with each operable independently or removable.

Abstract: A surgical aspiration system and the method of using the same for aspirating fluid from a surgical site at a desired aspiration rate. The system includes an interface component for providing an interface with the surgical site; a variable rate pump operably associated with the interface component for controllably generating a vacuum at the surgical site to cause a flow of fluids from the surgical site; a collector chamber interconnected with the interface component and with the pump for collecting liquids flowing from the surgical site; and a control system operably associated with the pump for controlling the pumping rate thereof in a manner to maintain the desired aspiration rate at the surgical site, the control system including a sensor for sensing a change in vacuum at the interface component due to liquid entering the interface component and for controlling the pumping rate of the pump in response thereto.

Abstract: This present invention covers novel means, devices and instruments for production of a tissue array block that is further sectioned into duplicates of tissue arrays. An integral microscope is incorporated into the instant instrument for viewing and examining a stained reference slide and selecting donor tissue core region(s) from the reference slide. The said reference slide is held in a reference slide station that is operatively linked and indexed with a station or platform holding a source donor tissue block, which is further indexed and precisely positioned with reference to the donor punch needle for punching the donor tissue core(s). A recipient block indexed to the donor block punch is placed under the donor punch station and donor tissue cores are delivered into pre-existing hole(s) by a stylet to construct the tissue array block.
